Arrangements for changing a vehicle, including a control unit which initiates the deployment of gears when an upper engine speed is exceeded or a lower engine speed is exceeded

摘要

An arrangement for changing gears in a motor vehicle has a control unit (12) for initiating selection of a particular gear. The control unit is designed so that it initiates a gear change when an upper or lower engine speed is exceeded or undercut. The threshold engine speeds for initiating a gear change are determined using a mathematical function based on at least two parameters that are dependent on the current engine operating state. An Independent claim is made for a method for initiating a gear change in a motor vehicle automatic gearbox.
